WORK-POSITIONING MEANS.

Application filed May 26, 1915.

To all whom it may concern:

Be it known that I, LOUIS M. BROWN, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain Improvements in fork-Positioning Means, of whichthe following description, in connection with the accompanying drawings,is a specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to shoe machinery and particularly to workpositioning-means or apparatus, and is herein shown as embodied in aconstruction designed foruse in a lasting machine of the type shown anddescribed in prior United States Letters Patent No. 1,018,477, grantedFeb. 27, 1912, on application of Matthias Brock. One object of theinvention is to improve the machine of said patent by facilitating theunjacking of shoes and eliminating danger of damaging high-toed shoeswhile they are being retracted in the machine during the unjackingoperation. A feature of the invention consists in a novel constructionand arrangement of mechanism constituting a work rest, with provisionfor relief of pressure between the work and the rest to facilitatewithdrawal of the work. In the illustrated embodiment of the inventionthe work rest comprises a support ing member and a work engaging memberhereinafter termed a face pad which is guided on the supportlng memberto move rearwardly and downwardly with reference,

to the position of a shoe supported bottom upward. The guiding means isconstructed and arranged to provide a stable condition of the face padin its elevated position and as herein shown the face pad is supportedto have a substantial range of backward movement on the supportingmember before it reaches a point where it is allowed to descend. Anadvantage in this construction is that the work rest in its normalcondition affords an effective support against clownward pressure on thebottom of the shoe.

A further feature of the invention consists in cooperating guiding meanson the supporting member and on the face pad constructed and arranged toprevent tipping movement of the face pad. These, guiding means are shownas consisting of grooves Specification of Letters Patent.

out in the side faces of'the supporting member and studs projecting intothe grooves and carried by depending side flanges of the face pad. Afurther feature of the invention consists in means for returning theface pad to normal relation to the supporting means and retaining itnormally in such relation. v i 7 These and otherfeatures of theinvention, including certain details of construction and combinations ofparts, will now be described with the aid of the accompanying drawings,which show an illustrative embodiment of the invention, and will then bepointed out in the claims. r V

Figure l in the drawings is a side elevation, partly in section, of somuch of a last 7 ing machine equipped with this invention as is ieede'dfor use in explaining the invention, an

Fig. 2 is a perspective view of the toe rest showing the face pad andits supporting member separated relatively in order better to illustratethe construction of each.

The work holding means of the illustrated lasting machine includes a toesupport A on which the toe portion of the shoe rests and a jackcomprising a heel pin B which enters the heel pin hole of the last andis movable supported and which has a roll standing on the periphery of acam 4 on cam shaft 5. In-the jacking operation, wherein the toe rest iselevated and the heel band is closed on the shoe, the spring 6 is putunder en. sion and in the unjacking operation that spring is releasedand effects the rearward movement of the heel pin to carry the shoebackwardly to position to be removed. The cam t supporting the toe restis also turned in the unjacking operation to allow the toe rest todescend but in practice the spring 6 acts to draw the heel'pin and theshoe back Wardly before the toe rest descends far enough to clear theshoe and, particularly if the last has a prominent toe, the shoe dragsover the rest. The mechanism and the general organization of the machinethus far briefly discussed are the same as fully shown and described insaid prior patent.

In accordance with the present invention there is provided for she-emaking apparatus, and incorporated in the type of lasting machine, shownin said prior patent, a toe rest comprising the supporting member 10 andthe face pad 12. The supporting member is a head formed on the stem 3and its top face includes, as best shown in Fig. 2, a horizontal face11, a downwardly and rearwardly inclined face 13 extending from the rearend of the face 11, a second horizontal face 14 extending from the lowerend of the inclined face 13, and a second inclined face 15 extendingfrom the rear end of the face 14:. 'The face pad comprises a cushion anda body portion which is formed with faces which are parallel to andcooperate with the faces 11, 13, 1 1 and 15, and said pad is adapted toslide on the supporting member rearwardly in a horizontal plane, seeFig. 1, through the length of the horizontal faces 11 and 1 1 and thento slide down the incline of faces 13 and 15 to the dotted line positionshown in Fig. 1. A spring 16 located in a slot in the supporting member10 and extending from an anchor therein to an anchor in face pad 12holds the face pad usually in full line position, Fig. 1, and returns itautomatically to the higher plane and to its normal longitudinalrelation to the supporting member 10 when the shoe has been disengagedfrom the face pad. The face pad is restrained from lateral displacementrelatively to the supporting member by flanges depending from the padand embracing said member. The pad is further guided, and is restrainedfrom tipping movement on said member, by studs 17, 18 which project fromthe flanges into guide grooves 20 cut into the opposite side faces ofthe supporting member and extending parallel to the faces 11, 13, 1e and15 on the top of said member. The faces 11 and 14: provide a normallyelevated position for the face pad of the toe rest in which it ismaintained at the same elevation while it may slide longitudinally ofthe machine as may be required during the operation of the machine, itbeing understood that the toe embracing mechanism is movable lengthwiseof the shoe and that the stem 3 of the toe rest is operatively con--nected with said mechanism for adjustment therewith lengthwise of themachine for shoes of different lengths. The inclined faces andparticularly the upper Walls of the grooves 20, guide and wedge the facepad downwardly as it is drawn rearwardly with. the shoe and into a planewhere the shoe can slide off from the face pad without objectionableresistance or danger of abrasion of the shoeleather.

It is to be understood that'the term face pad is not used herein in asense importing any limitation with respect to the character orconstruction of that part of the rest which contacts with the work, andthat such part may be variously constructed consistently with thepurposes and objects of the invention.

Having explained the nature of this invention and described anillustrative construction embodying the same, I claim as new and desireto secure by Letters Patent of the United States:
